FFmpeg supports encoding HEVC/H.265 since 2-12-2014 with libx265. Now you can use ffmpeg directly to encode HEVC or use another encoder than manually mux that into .mp4 using FFmpeg. Of course you can still use some patched FFmpeg build, but it is not recommended.
To make matters more confusing, there are two independent projects both named "x265", one by a Chinese college student and is practically dead, and another by a commercial company called MulticoreWare. Although the former started out first, it is practically dead now, and the latter is under active development and is supported by VideoLAN (the developer of x264).
Anyways, these are a complete set of current possibilities of encoding HEVC in order of my recommendation:
Directly using MulticoreWare libx265 with FFmpeg. This means with the latest Zeranoe build you can now do this:
ffmpeg -i INPUT -x265-params crf=25 OUT.mov
Using standalone MulticoreWare x265 and then mux the resulting file with FFmpeg.

Using DivX HEVC Encoder and then mux it.
Using standalone Chinese x265 then mux the resulting file with FFmpeg.
Using patched FFmpeg with Chinese x265 support.
Update: FFmpeg has HEVC encoding support using MulticoreWare libx265 now.

External libraries
x265
FFmpeg can make use of the x265 library for HEVC encoding.
Go to http://x265.org/developers.html and follow the instructions for installing the library. Then pass --enable-libx265 to configure to enable it.
x265 is under the GNU Public License Version 2 or later (see http://www.gnu.org/licenses/old-licenses/gpl-2.0.html for details), you must upgrade FFmpeg’s license to GPL in order to use it.

0002.安装x264
$git clone git://git.videolan.org/x264.git
$cd x264
$./configure --enable-static --disable-opencl --disable-avs --disable-cli --disable-ffms --disable-gpac --disable-lavf --disable-swscale
$make
$make install

0003.安装x265
https://bitbucket.org/multicoreware/x265/wiki/Home
# ubuntu packages:
$ sudo apt-get install mercurial cmake cmake-curses-gui build-essential yasm
# Note: if the packaged yasm is older than 1.2, you must download yasm-1.2 and build it
$ hg clone https://bitbucket.org/multicoreware/x265
$ cd x265/build/linux
$ ./make-Makefiles.bash
# 这里将 LOG_CU_STATISTICS　设置为ON，然后，按下“c”，实现configure，按下“q”退出
$ make
$ make install

0004.下载ffmpeg
从 http://ffmpeg.org/download.html 下载ffmpeg 2.1版本源码
$./configure --enable-libx264 --enable-libx265 --enable-gpl
